| Let us denote by the variable n the number of meters to which the length of the side a of this geometric figure corresponds.

Accordingly, according to the conditions from this problem, we can represent the sum of the sides a and b of this geometric figure in the form (n + 34).

Since we know, based on the conditions of this problem, that the value of the perimeter is one hundred and twenty two meters, then we write down the equation and calculate the length of the side a:

2 * (n + 34) = 122;

n + 34 = 61;

n = 27.

Answer: Under such conditions, the length will be 27 meters.
